Delta Air Lines is installing drag-reducing finlets across its fleet of 240 Boeing 737-800s and -900ERs following an extensive in-service evaluation with developer Vortex Control Technologies that ...

In 1980, a drilling mistake beneath a Louisiana lake triggered one of the strangest industrial disasters ever caught in memory. The water began spinning into a massive vortex that swallowed an $8 ...

(Top) Schematic diagram of the basic unit (Y-motif) of DNA condensates and their binding via sticky-end interaction. (Bottom) A schematic diagram illustrates how DNA condensate formation is regulated ...

Through the action of flapping, biological flyers generate a vortex upon each wing known as the leading-edge vortex (LEV), which has been shown to enhance aerodynamic force production. However, the ...

A1: Before answering your question, I'd like to tell you how the theory of vortex shedding was born, and share the role that fishing and Saint Christopher played in its discovery. An observant young ...

A two-dimensional vortex model is introduced in this paper in order to understand the characteristics of the shedding vortex in a blade-divergent passage and to mitigate or suppress it by appropriate ...

In this paper, an adaptive mesh refinement technique is presented for simulation of compressible flows, which can effectively refine the mesh in the regions with shock waves and vortices. The present ...
